Custom Glass Wool Roll

The Custom Glass Wool Roll is a versatile, high-performance insulation material designed for thermal and acoustic efficiency in modern buildings. As a type of glass wool roll, it is manufactured from inorganic glass fibers, resulting in a lightweight, resilient, and non-combustible product. It provides exceptional thermal performance (with low thermal conductivity), excellent sound absorption, and will not release toxic gases when exposed to fire, making it an environmentally responsible choice. Sunjoy offers this high-quality product in both standard and customized forms, including various facings like aluminum foil, to meet the specific demands of your project.

Aluminum foil faced glass wool insulation blankets will also be available.

Aluminum foil laminated glass wool blanket meets the market's high standard demand for green and environmentally friendly building materials, avoiding the harm of harmful substances such as formaldehyde and phenol to the human body and the environment. Moreover, aluminum foil laminated glass wool blanket can maintain good thermal insulation performance regardless of high or low temperature environment.

 

 

Custom Glass Wool Roll Service

Density & Thickness: We can adjust the nominal density (from 10 to 48 kg/m³) and thickness to meet specific thermal or acoustic targets.

Dimensions: Length and width can be tailored to your installation needs, reducing on-site waste.

Facing Materials: A wide range of facings is available, including aluminum foil, kraft paper, black tissue, PVC, vinyl, or we can work with you to develop a custom facing.

Packaging: We can customize the packaging type (vacuum, compression) and labeling to suit your logistics and handling preferences.

 

How to Choose The Glass Wool Roll

Determine Thermal Requirements: Calculate the needed R-value / thermal resistance for your climate and building code. This will dictate the required thickness and density.

Identify the Application:

• For walls and floors, a standard density roll (e.g., 14-18 kg/m³) is commonly used.
• For HVAC and ductwork, a foil-faced roll is essential for vapor control and condensation prevention.
• For metal buildings, consider options with reinforced facings for durability.

Consider Acoustic Needs: If sound control is a priority, all glass wool rolls provide excellent acoustic absorption, but specific densities can be optimized.

Check for Compliance: Ensure the chosen product meets local fire safety and environmental standards (e.g., non-combustibility, no toxic gas emission).

 

The Glass Wool Roll Comparison with Other Types

Feature	Custom Glass Wool Roll	Rock Wool Roll / Board	Rigid Foam Board (e.g., EPS/XPS)
Primary Material	Molten glass fibers	Molten stone/slag fibers	Polystyrene plastic
Structure	Flexible, fibrous roll	Fibrous (roll or semi-rigid board)	Rigid, closed-cell board
Thermal Performance	Excellent (low conductivity)	Excellent (slightly higher than glass wool)	Excellent (very low conductivity)
Fire Resistance	Non-combustible (Class A)	Non-combustible (Class A)	Combustible (may require fire barrier)
Acoustic Performance	Excellent (fibrous structure absorbs sound)	Excellent (denser, good for sound blocking)	Poor (can reflect sound)
Vapor Permeability	High (allows walls to breathe, unless foil-faced)	High	Low (acts as vapor barrier)
Ease of Installation	Easy to cut and fit in cavities	Can be slightly harder to cut; good friction fit	Requires precise cutting and sealing of joints

Custom Glass Wool Roll Packing

Common PE Bag: Standard packaging in polyethylene bags. This method is simple but occupies more volume.

Vacuum PE Bag (Recommended): The roll is compressed and vacuum-sealed in a PE bag. This significantly reduces volume, optimizes container loading, and lowers shipping costs.

Compressed PE Bag: A cost-effective compression method that reduces volume more than common bags, though the final packed size is larger than vacuum packaging.
